Automatic Screw Machine

An automatic screw machine, also known as an automatic lathe, is a fabrication tool used to make turned parts. Automatic screw machines are not controlled to the same extent as modern CNC lathes, however, they are still practical and cost efficient for small- and medium-sized parts. Automatic screw machines may have one or multiple spindles, though most machines are designed with multiple spindles capable of cutting multiple blocks of material.
